SO Colloquium – Origin and impact of protostellar outflows: the ALMA and JWST revolution

The birth of stars, and of planets around them, is universally associated with a spectacular bipolar ejection phenomenon that extends from stellar to parsec scales. Its manifestations include a narrow and fast axial jet, surrounded by a broader and slower molecular outflow carrying a large amount of mass.

The exact origin of these dual phenomena, their role in the removal of excess angular momentum, and their impact on star and planet formation, have all been a subject of fierce debate and active research over four decades.

In this talk, I will review major progress on these topics obtained from new observational facilities (from the optical to the millimeter range) and from enhanced modeling capabilities. In particular, I will highlight recent results from ALMA and JWST and how they could revolutionize our understanding of the origin and impact of protostellar outflows.
